Blackened Tempeh

I got the Real Food Daily cookbook the other day, I wish I could go there to eat, the menu looks incredible. I decided to make the blackened tempeh and the black bean and corn salad. It was so good. I did not add any oil to the marinade, it does not need it. I did have to spray the tempeh with olive oil in order for it to brown and crisp in the oven. I do love this cookbook but there is so much oil in all of the recipes, I don't think there is a need to add 1/2 cup of oil to every marinade, I just substitute veggie broth.
